    Summary: reading on uninitialized buffer can cause UB (`impl<R> BufRead for GreedyAccessReader<R>`)

    Details: Affected versions of this crate creates an uninitialized buffer and passes it to user-provided `Read` implementation. This is unsound, because it allows safe Rust code to exhibit an undefined behavior (read from uninitialized memory). The flaw was corrected in version 0.1.1 by zero-initializing a newly allocated buffer before handing it to a user-provided `Read` implementation.
